Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a processing circuit with device address setting signal input is used to control driver circuits, then the ability to selectively control specific semiconductor devices is improved, but the device complexity increases due to the need for address signal output circuits
Solution Approach 1:
The patent extracts the address signal output circuit from the processing circuit, making it a separate functional module. This allows the processing circuit to focus on control functions while the address signal output circuit handles address generation and distribution independently, thereby reducing the complexity burden on the main processing circuit.
Solution Approach 2:
The control system is segmented into distinct functional blocks: processing circuit, address signal output circuit, and driver circuits. Each segment has a specialized function, allowing independent optimization and simplification of individual components while maintaining overall system capability for selective device control.
2Ease of operation
If the processing circuit is disabled to simplify operation, then the ease of operation is improved, but the reliability decreases because the autonomous processing circuit may not maintain correct output settings
Solution Approach 1:
The autonomous processing circuit is designed to autonomously determine whether to output a normal drive signal or an abnormality notification signal based on received signals, without requiring constant supervision from the processing circuit. This self-service capability maintains reliability while allowing the processing circuit to remain disabled during normal operations.
Solution Approach 2:
The autonomous processing circuit is pre-configured with the capability to detect abnormalities and switch to notification mode in advance. This preliminary preparation ensures that when the processing circuit is disabled, the system can still reliably detect and respond to abnormal conditions without compromising output setting accuracy.
3Reliability
If the autonomous processing circuit is always enabled to maintain predetermined settings, then the reliability is improved, but the device complexity increases due to having two independent processing circuits
Solution Approach 1:
The autonomous processing circuit's operational state is dynamic rather than static. It can be enabled or disabled based on system conditions and processing circuit status. This dynamic configuration allows the system to have two processing circuits when reliability is needed while reducing complexity when the processing circuit is actively managing control.
Solution Approach 2:
The autonomous processing circuit serves multiple functions: it can maintain predetermined output settings, detect abnormalities, and generate notification signals. This multi-functionality reduces the need for separate dedicated circuits for each function, thereby reducing overall device complexity despite having an additional processing capability.
4Productivity
If signal processing is simplified by disabling the processing circuit, then the productivity is improved, but the measurement precision decreases because device address matching cannot be performed
Solution Approach 1:
The autonomous processing circuit acts as an intermediary that handles address matching and signal verification functions. When the processing circuit is disabled, the autonomous processing circuit intermediates between the address signal output circuit and driver circuits, ensuring accurate device address matching is performed without requiring the main processing circuit to be active.
